Currently there is no way to specify the preferred authentication
method for the HTTP backend and it always ends up with the CURL's
default
settings.
This patch enables it if supported by CURL, adding a couple of new
settings
and config environment variables listed below (the names within the
parentheses indicate the latter.)
- http.auth (GIT_HTTP_AUTH)
Specifies the preferred authentication method for HTTP. This can
be a method name or the combination of those separated by comma. Valid
values are "basic", "digest", "gss" and "ntlm". You can also specify
"any" (all of the above), "anysafe" (all of the above except "basic").
Note that the strings are treated case-insensitive.
- http.proxy_auth (GIT_HTTP_PROXY_AUTH)
Specifies the preferred authentication method method for HTTP proxy.
The same thing as above applies to this setting.
